Answer:
   A. 18 3/4
Step-by-step explanation:
It is convenient to rearrange the sum to make it easier to compute:
   7 3/4 + 4 3/4 + 6 1/4 = (7 3/4) +(4 +6) +(3/4 +1/4)
   = 7 3/4 + 10 + 1
   = 18 3/4

Answer:
Slope form of line  y = 9
Step-by-step explanation:
m= 3 
The y-intercept of the line that passes through the given point  (0,9) is
  9 = 3(0) + b
   b= 9
The equation of the line that passes through the given point  (0,9) is
 y =mx +b
  y = 0 +9
y=9
